11/06/2025: Rewards availability fix and improvements
🐛 Bug fix:
Fixed timezone bug that caused rewards to show as unavailable for use and drop out of the rewards profile a day early before users could click "Use now".
🔧 Improvements:
Changed the wording on the rewards cards from "Use by DD/MM/YY" to "Use by the end of DD/MM/YY" for clarity.
Changed the working of the profile so that rewards cards are always available for the user to select "Use now" until the very end of the final day of its availability.
